The actress’ A-list friends turned out in full force to celebrate her hubby’s birthday on Saturday night, donning onesies and playing beer pong to celebrate Cash Warren’s 38th.

“Love you babe!” Alba captioned a sweet Instagram pic of the couple in their comfy duds. “Last nights Pajama jammy jam was a blast! Love celebrating you with an epic pizza pajama game night! #happybirthdayCash.”
